"Estimating Sustainable Yields of Hawaiian Basal Aquifers by the modified Robust Analytical model(RAM2)" by Clark C.K. Liu, PhD, PE, F. ASCE professor of Civil & Environmental Engineering and researcher, Water Resources Research Center, University of Hawai‘i at Manoa

This seminar presents the formulation and application of the modified robust analytical model or RAM2 as a groundwater management tool for Hawaiian basal aquifers. The model is simple and all model parameters can be determined based on available deep monitoring well data. RAM2 consists of two sub-models; a flow sub-model and a transport sub-model.

The transport sub-model simulates the expansion of the transition zone as the head of a Hawai‘i basal aquifer declines and calculates the minimum equilibrium head of the aquifer, which is the head required to prevent seawater intrusion. The minimum equilibrium head can then be integrated with flow sub-model to determine the aquifer's sustainable yield. The reevaluation of the sustainable yields of two Hawaiian basal aquifers by RAM2 modeling, Iao aquifer on Maui and Kualapu‘u aquifer on Moloka‘i, will be discussed.
